I don't know if there is a way to do this, but if not, I'd like to request a feature :)

Occasionally on the forums, I'll do a search with 'author:Flick' to check up on any forum thread I might have responded to and lost track of. That doesn't seem to work for blogs. Is there a way to do a similar thing with blog comments? Searching for 'comment:Flick' or something would be nice. That, or just a way to view what comment threads I'm subscribed to. :)
